Electric hysterectomy device and assembling method thereof

Abstract

The invention discloses an electric hysterectomy device and an assembling method thereof.The electric hysterectomy device comprises an electric handle (1), an excision knife tube (2) is rotationally connected to the electric handle (1), uterus grasping forceps (4) are arranged on the inner side of the excision knife tube (2), a suction tube (3) is arranged on the outer side of the excision knife tube (2) in a sleeving mode, one end of the electric handle (1) is connected with the excision knife tube (2) through a driving part (5), and the other end of the electric handle (1) is connected with the uterus grasping forceps (4). The other end of the electric handle (1) is connected with an adapter ring (6) in a sliding mode, the end of the adapter ring (6) extends to the outer side of the electric handle (1) and is connected with a suction pipe (3), one side of the adapter ring (6) is connected with an operation button (7) located on the electric handle (1) through a transmission assembly, a liquid suction channel (8) is formed between the suction pipe (3) and the resection knife pipe (2), and one end of the liquid suction channel (8) is connected with a liquid suction pipe (9). According to the invention, the excision knife tube can be effectively prevented from being in contact with an external organ during excision operation, and hematocele suction of an excision part can be realized.

Description

technical field [0001] The invention relates to an electric hysterectomy device, in particular to an electric hysterectomy device and an assembly method thereof. Background technique [0002] In women's hysterectomy, it is often necessary to use a hysterectomy device to remove tissue in the uterus. The currently commonly used electric hysterectomy device is described in the patent 201922470627.4 "An electric hysterectomy device", which includes an electric handle connected to each other, a cutting knife tube, a puncture sleeve and a uterine grasping forceps. The working channel is established, and then the uterine grasping forceps pass through the resection knife tube and grab the tissue in the uterus. After grasping, the uterine grasper contacts the tissue with the cutting head of the resection knife tube, and then turns on the electric handle to drive the resection knife The tube rotates at a high speed in the working channel and cuts the tissue, so that the tissue and th...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain defects in the actual use of the electric hysterectomy device. One is that the cutting head of the cutting knife tube needs to be exposed to the outside of the puncture sleeve when rotating and cutting, so it is easy to interact with external organs during its rotation. contact, causing damage to external organs

The second is that a large amount of blood will be sprayed out during the cutting process, causing the blood to accumulate around the knife head and affect the doctor's field of vision

The current solution to this problem is to insert a suction device on one side of the electric hysterectomy device, and the blood accumulation at the cutter head will be sucked out by the suction device, but this method will undoubtedly increase the damage to the patient. For the narrow internal space, it is difficult to realize suction and cutting and grabbing operations at the same time, and there is some interference during suction

[0004] Therefore, the existing electric hysterectomy device has the problems of low cutting safety and difficulty in absorbing the fresh blood generated during resection.
